Elemental: The magnesium itself; the rest of the compound weight is the partner molecule.
Compound: The whole salt, such as magnesium glycinate, that must physically fit in the capsule.
Size 000: The largest standard capsule, about 1,100 mg of powder at 0.8 g/mL, the top of the usual 0.6–0.8 range; size 00 holds about 730 mg and size 0 about 545 mg.

Will 150 mg of taurate actually fit in one capsule, or do I need more than one?
Estimated salt mass versus assumed capsule capacity: Natural Rhythm Magnesium Taurate implies 841 mg of magnesium taurate in each capsule to deliver 150 mg of elemental magnesium, against 1,100 mg in the largest standard capsule (size 000) at powder density 0.8 g/mL, the top of the usual 0.6–0.8 range. Verdict: needs size 000, read at the most favourable hydration and the most units per serving.

How much elemental magnesium is actually in this label's filed magnesium lines?
Natural Rhythm Magnesium Taurate files 1 magnesium line in NIH DSLD 271261; the selected primary line declares 150 mg of elemental magnesium per serving, against 0 other rows excluded from the primary amount. A salt named under another nutrient does not turn that nutrient's quantity into elemental magnesium.

Does this label's taurate claim hold up, or could the magnesium come from another source?
The label names one magnesium form, taurate, resolved from the full NIH DSLD record text; at that salt the declaration is within the assumed size 000 capacity at powder density 0.8 g/mL, compared with oxide, the salt richest in magnesium at 60.3%.
